DUBLIN -- A woman who evaded arrest for two months after attacking a 73-year-old blues singer at a Hayward music festival surrendered to authorities Thursday morning and is being held on charges of felony assault and felony elder abuse, police said.

Dinalynn ¿Inez Andrews-Potter, 43, of Barstow, was charged Aug. 14 by the Alameda County District Attorney's Office but eluded law enforcement until she showed up at Santa Rita Jail and was booked, according to Alameda County Sheriff's office spokesman J.D. Nelson.

She remains jailed on $85,000 bail and is due Friday ¿afternoon at the Hayward Hall of Justice for her arraignment.

Lester Chambers, a Petaluma resident and former member of the 1960s soul group the Chambers Brothers, was performing at the Hayward Russell City Blues Festival about 5:15 p.m. July 13 when he dedicated Curtis Mayfield's hit "People Get Ready" to Trayvon Martin, the 17-year-old shot and killed by neighborhood watch volunteer George Zimmerman in Florida last year.

At the time, a Florida jury was still deliberating in Zimmerman's murder trial; they would acquit Zimmerman on a charge of second-degree murder about two hours later.

"Mr. Chambers is elated with that (news of the arrest)," said Oakland attorney John Burris, who is representing the musician in a $5 million lawsuit against the city of Hayward. "He's been waiting for this (arrest), so this is good news for him."

Witnesses told police that Andrews-Potter jumped on stage and yelled "it's all your fault" before shoving Chambers to the ground. The incident was caught on video by someone in the audience and later posted online.

Despite Chambers' injuries -- he was treated and released at a hospital for a welt on his backside, a bruised rib muscle, nerve damage and soreness, his son said after the attack -- Hayward police cited and released Andrews-Potter the same night. On Aug. 14, an Alameda County Superior Court judge issued a warrant for her arrest.

Burris said Chambers, who is slated to be inducted into the R&B Hall of Fame later this year, had to go back into the hospital earlier this week to be treated for significant bruising on his ribs. He has since been released, Burris said. "He's still achy but he's trying," Burris said.

Hayward investigators then reached out to Las Vegas officials for help tracking down Andrews-Potter, as she is well-known to authorities there.

Las Vegas officers performing a welfare check July 3 on Andrews-Potter discovered heavy smears of blood across two bedroom walls of her apartment, police said. Police determined that she had stabbed herself inside the residence.
